Male American artist and blogger.
In the 00's he was most notable for his activity in the Touhou fandom, including his Walfas-era fanart and the create.swf applet as well as his help as proofreader for the official English-translated script used in the Touhou doujin-anime by Tokine. More recently, he's become known for his chibi arts of various virtual YouTubers, mainly from Hololive English and Nijisanji EN; his particular caricature of Watson Amelia, dubbed Smol Ame, wound up being so popular that it's become a quasi-official mascot of Hololive in general.
Note that only art drawn by Walfie should be tagged with his name. Any other post made using create.swf should be tagged with the Walfas tag, and otherwise with Walfie (style).
